This is pretty cool! The tank just stays stationary until it is facing the target. What if it moved just a little, and as it faces more and more to the target, it moves faster and faster?

it seems the turnTowards() method was nearly added into the API of Actor . you may download the latest Greenfoot version and try again.

@Codex, above and to the right of the scenario window, you will see a large green button that says 'Open in Greenfoot'. Click on it to download the scenario. Move the scenario to a place you can read-write (your 'scenarios' folder would be the appropriate place). Then open that file up while running Greenfoot. You can open the source for the classes and view the code.
